First thing junk The wing bolt The threads do not fit the blind nut and it will pull out. You do not need a new wing just ream out the wing hole little to fit look at the bolt when laying down wing to make sure you are lined up with the hole on the fuse.. Sorry to say with most ARF the hardware has lot to be desered I would rather pay few more dollars and get better hardware then have to replace it all to get the Good stuff. I guess you get what you pay for. Good luck SL
